Ok, opened it, abit dusty inside, although not too horrible, going to clean it carefully there. The latest date code I could find is year 1998.
So here we are, few shots of it's gut, hope you will find it useful.
The top view, personally I love this kind of design that put all high voltage stuff at the rear, seen here it uses the green long stick at most right, connected to the front on/off push button.
View from the rear.
View from the front.
The firmware, Ver 1.4, its older version compared to HighVoltage's which is at 1.6.
I am kind of worry seing the battery, I'm guessing its for the volatile calibration data ? Sigh ... another "adventurous" battery replacement task again ? For sure I can not afford to send it to calibration lab, after looking at my buying price.
Analog front end section, no DC Option board like the one owned by HighVoltage. ... sigh ...
The RS-232 option board, looks like it provides full isolation for the serial connections.
An interesting big 22nF cap popped out in the middle analog section, wonder what is that for ? They could use a smd cap instead that big cap right ?
A bodge cap, I guess its earlier version.
